To ctZZ whom, it may concern..-

Be it known that I, HEINRICH Ponrfrnn, a subject of the King of Prussia,German Emperor, residing at Dortmund, Prussia, German Empire, haveinvented certain new and useful Improvementsin Coke-Ovens,of which thefollowing is a specification.

This invention relates to an improved cokeoven.

The best method of heating coking-ovens for obtaining by-prodncts isfrom above, as with this arrangement the heating-gases can pass to thewalls of the oven by the shortest path; The utilization oi the heat is,on account of the slow speed at which the heatinggases flow, greaterthan with other arrangements wherein the said gases are conveyed to andfro. Furthermore, any considerable differences of pressure in the wallsare avoid- 2o ed. Experiments hitherto made, however, have beenunfavorable to heating from above, as in all such constructionsoverheating of the upper portion of the oven of the gas-spaceoccurred,whereby the by-products were injured and the heating andlighting value of the gas diminished. In the arrangement which forms thesubjectof this invention the commencement of combustion is eiected belowthe level of the coke-charge, whereby the above-mentioned disadvantagesare avoided.

In the accompanying drawings I have illustrated an oven constructedaccording to the invention.

Figure 1 is a vertical longitudinal section through the oven, the lefthalf being a section on the line A B and the right half a section on theline C D of Fig. 2. Fig. 2 is a vertical section on the line E F, Fig.l.

l represents the coke ovens or chambers, 4o from which extend passages 2through the top wall 3, the air-chamber 4, and the roof or covering 5over the same.

6 represents air-inlets to the air-chamber.

7 8 are gas-supplies at opposite ends of the furnace and communicatewith pipe c at its opposite ends through pipes in which are cocks d.

9 represents heating or combustion chambers in the walls between theovens l, and 5o therein are several long partitions 10, which extendJfrom the bottoms of chambers 9 to near the tops thereof. The shorterpartitions ll extend from a distance above the bottom to a shortdistance below the tops of partitions l0.

a represents nozzles arranged directly over partitions 1l and receivegas from pipes c in the ro of above'the air-chambers. Pipes c are largerthan required to furnish the several nozzles a connected thereto. ThisIcauses pipe c to act as a reservoir, and gas will be supplied therefromin the same quantity to each nozzle. The gas which issues from thenozzles will strike directly on the upper edges of partitions l1.

b represents openings through the top walls of chambers 9 alongside ofthe nozzles in position to be also directly over partitions 1l, so thatcurrents of air and gas commingle above the partitions 1l or strike onthe upper edges of said partitions and are thus commingled. As shown inFig. 2, openings l) are contracted at the bottom by the slight inwardbends b in the rear walls of the grooves which form openings b.

Since a large number of nozzles or burners ce are used, the heating ofthe oven-walls and the chambers l is regular, whereby decomposition inthe chambers is more quickly effected and the ovens are increased indurability.

I claim- 1. The combination of coke-oven 1, heating-chamber 9,partitions 10, ll, in the heating-chamber, nozzles in the top of chamber9 above partitions ll, gas-pipe c communicating with the nozzles, meansfor supplying gas to both ends of pipe c, an air-chamber 4 above theoven, air-passages beside the nozzles and inclined toward each other sothat the air and gas currents meet and commingle above partitions 1l, asset forth.

2. The combination of coke-oven l, heating-chamber 9, partitions l0, ll,in the heating-chamber, nozzles in the top of chamber 9 above partitionsll, gas-pipe c communicating with the nozzles, pipe o being of largercapacity than that required by the combined iow through its severalnozzles a, thereby serving as a gas-reservoir, means for supplying gasto both ends of pipe c, an air-chainber Il above the oven, air-passagesbeside the nozzles and inclined toward each other so that the air andgas currents meet and commingle above partitions 11, as set forth.

3. The combination of coke-oven l, heat- IOO ing-chamber 9, partitions10, 1l, in the heating-chamber, nozzles in the top of chamber 9 abovepartitions 1l, gas-pipe c communicating'With the nozzles, means forsupplying gas to both ends of pipe c, an air-chamber 4 above the oven,air-passages beside the nozzles and inclined toward each other so thatthe air and gas currents meet andcommingle above partitins 11, as setforth, said nozzles extending below the tops of the coke-ovens. y roSigned at Dortmund, Germany; this 25th day of January, 1899.
